ebm-papst technology meets tomorrow’s standards today.
All ebm-papst fans with GreenTech EC technology already far surpass the efficiency standards likely to come into force from 2020 onwards. We call this “ErP Next – the future of efficiency now”. For our customers it is a guarantee of highly efficient, future-proof high-end products conforming to legal requirements.

Decentralized residential ventilation Decentralized ventilation systems provide healthy, low-energy air circulation. Installation is straight forward, and retrofitting in existing buildings is no problem. It merely involves fitting fans in the outside walls to extract stale or moist air from rooms with a particularly humid atmosphere, such as bathrooms. A fan then draws the air out of this room and fresh air flows in.
1 Decentralized ventilation unit with heat recovery These can be fitted in specific rooms and controlled individually. An optimum flow of air is ensured by powerful tubeaxial fans of axial, centrifugal or diagonal design, for example reversible axial fans or particularly quiet-running centrifugal fans.

Pairs of fans for supply and exhaust air are integrated into the window frame. DC centrifugal fan/DC axial fan – Electronically commutated drive with electronic reverse polarity protection – Less thermal impact and longer service life – Optimized noise emissions 4 Ventilation unit with heat recovery Compact design, high heat exchange efficiency, low power requirement.

Central residential ventilation With central ventilation systems, one central unit is responsible for air exchange for the entire building. Various different concepts exist. These range from simple air supply/exhaust units to solutions featuring integrated heat recovery and hybrid solutions with additional heat pump units.
5 Roof-top heat recovery system The warm, “stale” exhaust air from kitchens and bathrooms is routed out of the building via a central duct through the roof. A ventilation unit with heat recovery is connected to this exhaust air duct. The heat is extracted from the exhaust air and then used for heating purposes. Centrifugal fans RadiPac and RadiCal – High, static overall efficiency – Aerodynamically optimized impeller – Maintenance-free and quiet-running – Infinitely variable control characteristics 6 Central ventilation system with heat recovery One centrifugal fan each conveys the supply air and the exhaust air via a heat exchanger in which the cold outside air is pre-heated by the warm, stale exhaust air. The air is thus at a pleasant temperature when supplied to the rooms. Centrifugal fans with backward- or forward-curved blades – Enhanced air performance – Higher impeller efficiency – Considerable noise reduction – Operation with a constant air flow 7 Home ventilation combined with heat pump The air/water heat pump uses outside air to heat the inside of the building. Heat pumps are suitable for universal use. They can be installed both in gardens and in cellars. Axial fan HyBlade and centrifugal fan RadiCal – Maximum energy efficiency – Minimum noise generation – Intelligent control – Innovative flow-optimized design 8 Exhaust air/outgoing air heat pump The heat pump draws in the warm air in the room and extracts energy from it to heat the service water tank. The exhaust air is routed out of the building and a corresponding amount of fresh air flows in through defined air supply vents. Centrifugal and axial fans with GreenTech EC motors – High efficiency – Demand-based speed adjustment – Low noise generation
